Abstract
A series of Co–Mn–Al mixed oxides modified with alkali metals (Li, Na, and K) were prepared from Co–Mn–Al layered double hydroxide and tested for N2O catalytic decomposition in inert gas and in the presence of oxygen. Chemical analysis, XRD, N2 sorption, TPD-O2 and TPD-N2O were used to characterize the catalysts. During TPD-O2, higher amount of O2 was desorbed from more active catalysts. The extent of O2 inhibition related to the degree of surface coverage by oxygen.
